Embodiment 1
[0039] Preparation of ethylene glycol diester of acrylate-1-adamantanecarboxylate
[0040] After adding 2g of hydroxyethyl acrylate, 2.6g of triethylamine and 100mL of dichloromethane into a three-necked flask with a mechanical stirring device, the reaction temperature was 0-5°C, and 4.1g of 1-adamantanecarbonyl chloride was weighed, Then dissolve it in 40mL of dichloromethane, drop it into a three-necked flask within 3 hours, after the dropwise addition, continue to stir for 5 hours, let it stand overnight, and filter it with suction to obtain a light yellow liquid, which is washed with dilute hydrochloric acid solution (1mol / L), NaHCO 3 (1mol / L) solution and distilled water to wash the light yellow liquid (retained liquid is the upper layer), and use anhydrous Na 2 SO 4 Dry, filter, and remove the solvent to obtain a light yellow acrylic acid-1-adamantanecarboxylic acid ethylene glycol diester solid, whose structural formula is as follows

[0044] Preparation of ethylene glycol diester of acrylic acid-3-formyl chloride-1-adamantanecarboxylate
[0045] After adding 2g of hydroxyethyl acrylate, 2.6g of triethylamine and 100mL of dichloromethane into a three-necked flask with a mechanical stirring device, the reaction temperature is 0-5°C, and weigh 5.4g of 1,3-adamantanedi formyl chloride, and then dissolved in 40mL of dichloromethane, drop it into the three-necked flask within 3 hours, after the dropwise addition, continue to stir for 5 hours, let it stand overnight, and filter it with suction to obtain a light yellow liquid, which is washed with dilute hydrochloric acid Solution (1mol / L), NaHCO 3 (1mol / L) solution and distilled water to wash the light yellow liquid (retained liquid is the upper layer), and use anhydrous Na 2 SO 4 Dry, filter, and remove the solvent to obtain a light yellow acrylic acid-3-formyl chloride-1-adamantanecarboxylic acid ethylene glycol diester solid, whose structural formula is as fo...
Embodiment 3
[0049] Preparation of ethylene glycol diester of methacrylic acid-1-adamantanecarboxylate
[0050] After adding 2g of hydroxyethyl methacrylate, 3.3g of tripropylamine and 200mL of dichloromethane into a three-necked flask with a mechanical stirring device, the reaction temperature is 0-5°C, and weigh 3.7g of 1-adamantanecarbonyl chloride , and then dissolved it in 60mL of dichloromethane, and dropped it into a three-necked flask within 3 hours. After the dropwise addition, continued to stir for 5 hours, left it standing overnight, and filtered it with suction to obtain a light yellow liquid, which was washed with dilute hydrochloric acid solution ( 1mol / L), NaHCO 3 (1mol / L) solution and distilled water to wash the light yellow liquid (retained liquid is the upper layer), and use anhydrous Na 2 SO 4 Dry, filter, and remove the solvent to obtain a light yellow methacrylic acid-1-adamantanecarboxylic acid ethylene glycol diester solid, whose structural formula is as follows
